Japan's tech scene tonight reads like a tug-of-war between the new and the entrenched. Cloudflare is turning its AI Search into an embedded, agent-native retrieval layer — the interesting bit being that it's aimed squarely at companies' own custom data rather than the public web, which is where AI agents actually get stuck. Meanwhile Arm's three-product splash at Arm Everywhere China (CSS for Mobile 2, Total design for Physical AI, Neoverse CSS N4) quietly redraws the roadmap: mobile-first silicon with a stated PC trajectory and a Physical AI play, with the C2-Ultra core claiming roughly 15% more single-thread speed at 12–15% lower power than the C1-Ultra — a meaningful efficiency step for edge AI. On the ground in Japan, Yamaha Motor is shifting its all-aluminum DiASil cylinders from virgin material to recycled aluminum alloy while rolling out hydrogen equipment domestically, and six parties including Koshigaya city and Anker Japan are demonstrating safe collection of used lithium-ion batteries to stop the rising tide of fires at waste facilities and recover rare metals — decarbonization and circularity moving from pledges to plant-floor decisions. Enterprise IT, though, shows how slowly incumbents move: Mizuho Bank found a way to keep running end-of-life RHEL without upgrading or migrating at all, dodging the usual churn. And Nulab's developers open-sourcing "bee," a CLI for operating Backlog, is a small reminder that Japan's software craft culture still ships tools the open-source way.

1. Cloudflare、AI Searchを拡張し、エージェントや開発者によるカスタムデータ検索を容易にする機能を追加
   
   (Cloudflare Expands AI Search, Adding Features That Make Custom Data Search Easier for Agents and Developers)
   
   (InfoQ Japan)
   
   Cloudflare has expanded its AI Search service, an embedded search-and-retrieval product designed so AI agents and applications can immediately use a search engine against an organization's own custom data. The update adds support for integration with agents and multimodal search, alongside seamless linkage with Cloudflare's other tools — a bid to make private-corpus retrieval a plug-in utility for agent builders rather than a custom integration project.
2. ArmのCSS for Mobile 2はPC向けの伏線!?　Neoverse CSS N4はAGI CPUと競合せず
   
   (Is Arm's CSS for Mobile 2 a Prelude to PCs?! Neoverse CSS N4 Won't Compete with AGI CPUs)
   
   (Monoist)
   
   Arm used its September "Arm Everywhere China" event to unveil three products — Arm CSS for Mobile 2, Arm Total design for Physical AI, and Arm Neoverse CSS N4 — signaling a roadmap that stretches from mobile silicon toward PCs and physical-world AI. The new C2-Ultra core claims roughly 15% higher single-thread performance and 12–15% lower power than the C1-Ultra, while an SME2 unit is credited with 5–7 TOPS at just 1–2W TDP, targeting on-device AI workloads.
3. ヤマハ発動機が主力シリンダーにリサイクルアルミ採用、水素設備も国内から実装
   
   (Yamaha Motor Adopts Recycled Aluminum for Flagship Cylinders; Hydrogen Equipment Also Rolled Out Domestically)
   
   (Monoist)
   
   Yamaha Motor announced it will progressively switch the raw material of its all-aluminum DiASil cylinders from virgin stock to recycled aluminum alloy, while also moving forward with implementing hydrogen equipment starting in Japan. The company framed both moves as part of a progress update on its environmental technology efforts — concrete decarbonization decisions at the manufacturing layer rather than distant pledges.
4. 使用済みリチウムイオン電池の発火を防ぎ、レアメタルを回収する実証開始
   
   (Demonstration Begins to Prevent Fires from Used Lithium-Ion Batteries and Recover Rare Metals)
   
   (Monoist)
   
   Six parties including Koshigaya city and Anker Japan have launched a demonstration project to build a safe collection system for used lithium-ion batteries. The effort tackles two concrete problems: the growing number of battery fire incidents at municipal waste-processing facilities, and consumers not knowing where to dispose of batteries — while also creating a recovery channel for rare metals that would otherwise be lost.
5. みずほ銀行が“サポートの切れるRHEL”を「アップグレードも移行もせず」安全に継続利用　その方法は？
   
   (Mizuho Bank Keeps Running RHEL Past End-of-Support "Without Upgrading or Migrating" — How?)
   
   (ITmedia AIT Linux)
   
   Mizuho Bank avoided the usual end-of-life burden entirely, finding a way to keep operating its RHEL systems past their support deadline safely — with no OS upgrade and no migration to another platform. The case study walks through the bank's method, offering a playbook for enterprises that need continuity without the disruption and cost of wholesale platform changes.
6. BacklogをCLIから操作　ヌーラボ開発者が「bee」をOSSで公開
   
   (Operate Backlog from the CLI: Nulab Developer Open-Sources "bee")
   
   (ITmedia AIT Linux)
   
   A developer at Nulab has open-sourced "bee," a command-line tool for operating Backlog, the company's project management service. The release lets developers manage issues and tasks from the terminal instead of the browser — a small but welcome nod to keyboard-driven workflows, and a reminder that Japan's dev-tool scene still contributes back to the open-source commons.
